| Abstract | In this paper, the analysis is performed on Thomson coil actuator and the dynamic characteristics is presented, which is necessary to the fast switch of HVDC circuit breaker. For analysis, electromagnetic and dynamic equations are simultaneously solved using commercial code. Whole geometry with a drive coil is simplified and applied to analysis by considering the cylindrical shape of the actuator for simulation. In calculation of current flowing through the coil as the component of electric power circuit for operation of the actuator, the resistance and the inductance are taken into account, including stray component. The calculated current is used to predict the repulsive force on the plate, and the stroke of the actuator is deduced from solving the dynamic equation by considering the forces by spring and the gravity besides friction. Through simulation, dynamic variables are calculated such as inductance of a drive coil, force on a repulsive plate, and so on. Also, flux lines, induced current density, and magnetic flux density are predicted to time. In order to confirm the simulation results, experiments are performed for the prototypes with simple contacts and a vacuum interrupter, which is designed for fast switch. Experimental results are compared with simulation and the characteristics are discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
